I like your FOs. Pretty colors, bet your mom will be glad to get them.
Scented yarn? I got stinky lavender yarn by mistake, got it home and when I was working with it, I kept trying to figure out where that smell was coming from, it was on my hands and I couldn't figure it out. I finally realized it was the yarn. Never again! What's more, it didn't wash out the first time I ran it through the wash either. Yuck.
I should never overestimate my basic arithmetic skills.
